Novel clinical medicine metering device for department of pediatrics

Abstract

The invention provides a novel pediatric clinical medicine metering device which comprises a mounting shell, a medicine storage cylinder and a metering cylinder, scale marks are arranged on one side of the metering cylinder, the medicine storage cylinder is connected with the metering cylinder through a medicine feeding pipe, a first one-way valve is arranged on the medicine feeding pipe, and a second one-way valve is arranged at the bottom of the metering cylinder; a mounting frame is arranged on the metering cylinder, the two ends of the crank are rotatably connected with the two sides of the mounting frame respectively, a lifting gear connected through a speed change assembly is arranged at one end of the crank, a piston plate is arranged in the metering cylinder, the lifting gear is meshed with a rack on the piston plate, a mounting disc is arranged at the bottom of the inner side of the mounting frame, and a threaded cylinder is arranged on the mounting disc; and one end of the threaded rod is provided with an adjusting wheel, and the other end of the threaded rod is rotatably connected with a limiting ring. The device can be used for conveniently, quickly and accurately metering liquid medicine, the volume of the liquid medicine is convenient to adjust, and the operation is more convenient. And the situation that the volume of the liquid medicine which is weighed every time is the same but the concentration of the liquid medicine is different can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more particularly relates to a novel pediatric clinical medicine doser. Background technique [0002] In the treatment of children, in order to facilitate the feeding of medicines, it is necessary to grind the medicines into a powder-like structure, and dissolve them in warm water when taking them. Due to the special constitution of children, the dosage of medicines needs to be strictly controlled to avoid overdose or underdose. Occurs, so it is necessary to use a dedicated medicine dispenser to measure the medicinal liquid with the medicine. [0003] For example, the Chinese patent with the patent number of 202122233056.X provides a medicine doser for clinical use in pediatrics. The doser makes the medicine liquid flow out from the bottom of the first doser and the second doser by rotating the one-way valve for weighing, The micro-motor can also be started to drive the stirring rod ...
